Definitions
- the present invention relates to facing materials for absorbent products, and specifically to clean, dry facings for sanitary napkins.
- Facing layers have long been used in absorbent products to contain the absorbent core media and provide a surface for contacting the skin.
- Initially facings were developed for their softness, absorbency, and bulk or cushioning effect. Facings have also been developed which have improved fluid transfer properties. These facings have been characterized by a reduced rate of absorbency and reduced strike back of fluid from the absorbent core.
- U.S. Patent 4,391,869 which describes a low density fabric comprising a web of resin bonded synthetic polyester staple fibers. The fabric is saturation bonded and may be subject to conventional after treatments, including a repellent coating. Due to the overall binder coating, this fabric if repellent coated would not exhibit the enhanced repellency or stain resistance of the facing of the present invention.
- Apertured plastic films have also been used in facings to reduce strike back, however, they have typically been used in conjunction with fabric layers to give the facing a cloth-like surface feel. Though a "plastic feel" is not desired in a facing, when apertured plastic films have been used as the top surface of a facing, the facings exhibit a clean dry surface, due to the repellent or hydrophobic properties of the plastic.
- One such facing is described in U.S. Patent No. 4,324,246.
- GB-A-2153229 and GB-A-2103933 both disclose cover layers having a plurality of perforations therethrough.
- the facing of the present invention is a repellent fibrous facing, which exhibits a clean, dry surface, without the "plastic feel" of an apertured plastic film facing.
- the enhanced repellency of the facing is achieved by a repellent top coat on a fibrous layer with only an intermittent binder coating.
- the present invention comprises a nonwoven facing material with improved stain resistance, and a method for making the same.
- the facing material is useful as a facing for absorbent products, and particularly for sanitary products.
- the facing material of the present invention comprises a web of hydrophobic staple fibers, intermittently bonded with an absorbent cured binder material, and top coated with a repellent material, preferably a fluorochemical repellent material.
- the web of hydrophobic fibers is apertured prior to the application of binder and repellent.
- the apertured web may be produced by the fluid rearranging process described in U.S. Patent No. 2,862,251, wherein the fibers are rearranged into a pattern of yarn-like bundles defining a pattern of apertures therebetween.
- the web When the web is apertured in this manner, it is preferred that the web contain approximately 5% to 20%, and most preferably 12% by weight of rayon staple fibers.
- the facings of the present invention exhibit improved repellency and stain resistance in terms of both stain area and stain intensity.
- Figures 1-7 are 5x photomacrographs of various fibrous facing materials.
- the facing material of the present invention is made from a starting web comprising hydrophobic fibers, such as polyester, acrylic, orlon, or nylon staple fibers.
- the web may comprise carded fibers, randomly arranged fibers as in an air-laid web, or a combination thereof.
- the web of fibers is intermittently bonded with an absorbent binder material, and top coated with a repellent material.
- intermittent bonding refers to a binder pattern on the final fabric in which, after curing, the binder areas are well spaced from each other. Such a pattern may be achieved with a rotogravure roll with a diamond or diagonal pattern of print lanes with 6 lines per inch (2.4 lines/cm).
- the pattern of cured binder areas in the fabric may depend on many factors, including the pattern of application of the binder, the amount of binder added and the degree of migration of the binder, however, one skilled in the art is readily able to design and achieve an intermittent pattern of cured binder in a fabric.
- the binder areas in the facing fabric of the present invention should comprise approximately 20% to 50% of surface area of the fabric.
- the absorbent binder used may be any one of the commercially available absorbent binders such as National Starch 4260 acrylic binder. B.F. Goodrich 2671 acrylic binder, or National Starch 125-2873 vinyl acetate/acrylic copolymer absorbent binder.
- the repellent may be any of the commercially available repellent materials such as the wax based solutions or emulsions, but is preferably a fluorochemical repellent material.
- the web is apertured for improved fluid strike through.
- the starting web may be apertured by the fluid rearranging method described in U.S. Patent No. 2,862,251 which produces a web comprising yarn-like bundles of fibers with a pattern of apertures therebetween.
- the web comprises approximately 5% to 20%, and most preferably 12% by weight of rayon staple fibers for enhanced aperture clarity.
- rayon/polyester fabrics of 25, 75 and 100 percent polyester fibers show gradually increasing stain resistance, a fabric of 88% polyester and 12% rayon exhibits a further increase in aperture clarity and stain resistance.
- the facings of the present invention are repellent and show improved stain resistance in terms of reduced stain area and stain intensity. Surprisingly, this improved stain resistance is achieved with the use of an absorbent binder. As set forth in the following Table, the facing of the present invention exhibits greatly improved stain resistance over fabrics made with repellent binders, and those made with an overall application of absorbent binder.
- these facings may be used in a product for absorbing body fluids comprising an absorbent core, and the facing material overlying said absorbent core.
- Such products include sanitary napkins, diapers or bandages.
- the facing material may be adhered to the surface of the absorbent core, for example with a hot melt adhesive or an emulsion adhesive.
- the facing material may be adhered to the absorbent core in an overall pattern or the facing material may be adhered to the absorbent core in a striped pattern.
- the facing material and the absorbent core may contain thermoplastic material, and the facing material may be heat bonded to the absorbent core.
- the fabric of Sample 1 shown at 5x in Fig. 1, has a stain area of 4.4 sq. in. (25.8 cm2) and a stain intensity of 23.4 as measured on a Hunter Colorimeter, as described below.
- Sample 1 is a 260 grains/yd2 (20 g/m2) card and bind fabric, consisting of 220 grains/yd2 (17 g/m2) of a fiber blend of 50% Avtex SN 1913 rayon staple fibers and 50% Celanese 417 polyester staple fiber, with an overall coating of 40 grains/yd2 (3.1 g/m2) of B. F. Goodrich 2671 acrylic absorbent binder. As may be seen in Fig. 1, this fabric exhibits a large, intensely colored stain and hence is not stain resistant.
- Sample 2 shown at 5x in Fig. 2, is a 325 grains/yd2 (25 g/m2) fabric consisting of 212 grains/yd2 (16 g/m2) of a carded web of a blend of 50% 1.7 denier 1.5 inch (3.8 cm) Lenzing Lenzesa rayon and 50% 1.7 denier 1.5 inch (3.8 cm) DuPont 372 polyester fiber rearranged according to the method of U.S. Patent 2,862,251, at 120-130 psi (827-896 kPa) water pressure on a drum with 165 holes/in2 (25.6 holes/cm2). Thereafter, 113 grains/yd2 (9 g/m2) of binder solution is foamed into the web to provide an overall coating of binder.
- 113 grains/yd2 (9 g/m2) of binder solution is foamed into the web to provide an overall coating of binder.
- the binder used is National Starch 125-2873 vinyl acetate/acrylic self cross linking copolymer absorbent binder with 11 grains of repellent micro-crystalline wax emulsion with Zirconium salts, which renders the binder solution repellent.
- Sample 2 shows only slight improvement in stain area and intensity over sample 1.
- Sample 3 shown at 5x in Fig. 3 is a 285 grains/yd2 (22 g/m2) fabric consisting of 228 grains/yd2 (18 g/m2) of a carded web of a blend of 88% by weight Celanese D-244 1.2 denier 1.5 inch (3.8 cm) polyester staple fiber and 12% by weight Avtex SN 1913 1.5 denier 1 1/8 inch (2.86 cm) Rayon staple fiber, with 56 grains/yd2 (4.3 g/m2) of binder solution of National Starch 4260 acrylic absorbent binder, rendered repellent with I.C.I. F-31X fluorochemical repellent.
- the fibers were rearranged with 120-130 psi (827-896 kPa) of water, at 120-130° F. (48.9-54.4°C) using a 73.4 x 73.4 belt and a drum with 144 holes/in2 (22.3 holes/cm2), prior to the addition of the binder solution, applied with a rotogravure roll at 23 lines per inch (9 lines/cm) to achieve overall saturation bonding.
- the fabric was top coated with ICI F-31X repellent in a padder operation resulting in 1 grain/yd2 (77 mg/m2) repellent coating.
- the sample has a stain area and intensity similar to sample 2.
- Sample 4 shown at 5x in Fig. 4 is a 350 grains/yd2 (2.1 g/m2) fabric consisting of 242 grains/yd2 (19 g/m2) of a carded web of Hoechst T-221 1.25 denier 1 1/2 inch (3.8 cm), polyester fiber rearranged as sample 3, with 97 grains/yd2 (7.5 g/m2) of a binder solution of Rohm & Haas NW-1284 repellent acrylic binder to which TiO2 has been added for fabric opacity.
- the binder solution is applied with a 23 line per inch (9 lines/cm) rotogravure roll to achieve overall binder saturation.
- the fabric After curing, the fabric is top coated with a 3M FC-824 fluorochemical repellent in a padder operation resulting in a 1 grain/yd2 (77 mg/m2) repellent coating.
- the sample shows some improvement in stain area and intensity, but is difficult to produce as the TiO2 is difficult to maintain in solution and dries quickly, fouling the lanes of the rotogravure roll.
- Sample 5 shown at 5X in Fig. 5 is a 280 grain/yd2 (22 g/m2) fabric consisting of 229 grains/yd2 (18 g/m2) of a carded web of a blend of 88% by weight Celanese D-244 1.2 denier, 1.5 inch (3.8 cm) polyester staple fiber containing 1.5% TiO2, and 12% by weight of Avtex SN-1913 1.5 denier 1 1/8 inch (2.86 cm) rayon staple fiber rearranged as sample 3, with 50 grains/yd2 (3.9 g/m2) of National Starch 4260 acrylic absorbent binder applied with a rotogravure roll at 23 lines/in (9 lines/cm) to achieve overall saturation bonding.
- the fabric After curing the binder, the fabric is top coated with I.C.I. F-31X repellent in a padder operation resulting in a 1 grain/yd2 (77 mg/m2) repellent coating.
- This sample shows similar stain area and intensity to sample 4.
- Sample 6 is a 280 grains/yd2 (22 g/m2) fabric consisting of 229 grains/yd2 (18 g/m2) of a carded web of the fiber blend of sample 5 and 50 grains/yd2 (3.9 g/m2) of National Starch 4260 acrylic absorbent binder, rearranged as sample 3.
- the binder is applied with a rotogravure roll in a diamond pattern of 6 lines in (2.4 lines/cm) at a 30° angle, the lanes of the print roll being 0.014" (0.35 mm) wide and 0.004" (0.1 mm) deep. After curing the binder, the fabric is top coated with I.C.I.
- F-31X repellent in a padder operation resulting in a 1 grain/yd2 (77 mg/m2) repellent coating The sample exhibits an unexpected strain resistance, with a stain area of only 3.5 sq. in. (22.6 cm2) and a stain intensity of only 4.8
- Sample 7 is a 280 grains/yd2 (22 g/m2) fabric of a 229 grain/yd2 (18 g/m2) carded web of the fiber blend of samples 5 and 6, rearranged as sample 3, with 50 grains/yd2 (3.9 g/m2) of Rohm and Haas 1715 repellent binder applied with the same rotogravure roll as used in making sample 6. After curing the binder, the fabric is top coated with I.C.I. F-31X repellent in a padder operation resulting in a 1 grain/yd2 (77 mg/m2) repellent coating. The sample exhibits a stain area and intensity similar to sample 5.
- the above Table demonstrates the unexpected stain resistance of the facing of the present invention, comprising hydrophobic fibers intermittently bonded with an absorbent binder, and top coated with a repellent finish.
- the facing material of the present invention may be used as the facing layer of absorbent products such as sanitary napkins. When used as a facing layer, the facing material may be juxtaposed to the top surface of the absorbent core of the napkin, with or without an intervening fibrous layer, such as tissue, and may be glued in place or merely positioned on the napkin.
- the facing material may be wrapped around the absorbent core, and a fluid impervious layer may be positioned in the napkin beneath the absorbent core.
